SONIC VI: Silicon MKI Tone Bender

Sonic VI silicon MKI eyelet layout v2A 2765fc4de3aa

The SonicVI silicon MKI Tone Bender is firmly based on the original, with a few additions and some minor changes.   Being silicon based, the transistors do not self-bias, so additional resistors have been added from V- to the base of Q1 & Q3.  The transistors used are early Mullard PNP silicon OC202 which are quite … Read more

VERO: Getting Started Building DIY Guitar Effects – Vero Layout Guide

VERO LAYOUT GUIDE V1 ce31b231a647

I’ve had a few questions lately via Instagram about some basics on my vero layouts – while this doesn’t cover everything, I hope it helps clarify a few things for people just starting out.  Essentially, my vero layouts are functionally the same as many others, the key differences being the use of colour coding, and … Read more

The Equinox is Spaceman’s trimmed-down version of an old-school studio equaliser – it’s definitely inspired by Pultec, but with a few key differences.  I’m fine with the differences, as it makes it practical to build. Schematic can be found here on PedalPCB.   If you don’t have a power supply that kicks out 18v, Dirtbox … Read more

INTERFAX: Harmonic Percolator (modded)

Interfax Harmonic Percolator with mods vero layout v1a 3903a08c8f20

This is a slightly modded Interfax Harmonic Percolator that I made today.  It’s an odd little circuit – it can run from clean, a bit overdriven, then into distortion, and finally to overly compressed fuzz madness.  The range of sounds are so broad, it’s almost worth setting it up as a dual pedal (which I … Read more

WEM Project V / Ghost Warmjet – Modded Layout

BE warmjet V2a vero layout 3a461c46b297

 I have a fairly extensive post on the Wem Project V here, this is post is primarily to document my own work, as I’m not sure how many people would want to build in this style.  Standing resistors are mostly frowned upon in the world of vero, despite being commonplace on many vintage effects.   Joining … Read more
